A Microsoft MVP -- Most Valued Professional -- and Windows expert has sent company CEO Steve Ballmer a letter asking him to look into the worrisome trend of sub-standard patches that crippled computers, forced IT personnel to scramble to undo snafus and damaged Microsoft's hard-earned reputation.

Susan Bradley, one of the moderators of the Patchmanagement.org email list -- called a "listserv" -- who also frequently offers free advice on Microsoft's support forums and writes a weekly column on patching for the "Windows Secrets" newsletter, posted her Ballmer letter to the list last Wednesday.

"On behalf of everyone in this community, may I respectfully request that you assign someone in a management position to investigate what is going on with quality control with patch testing lately?" Bradley asked Ballmer.

"This month in particular leaves me deeply disturbed that issues that should have been found before these updates were released are being found by us -- your customers -- after they are released and we are having to deal with the aftermath," Bradley continued. "Bottom line, sir, this is unacceptable to all of us in the patching community, and quite frankly, it should be just as unacceptable to you."

Microsoft's patch problem goes further back: In August, the Redmond, Wash. company yanked an Exchange security update, admitting it had not properly tested the patches. And in April, Microsoft urged Windows 7 users to uninstall an update that crippled PCs with the infamous "Blue Screen of Death;" it re-released the update two weeks later.

While Bradley hasn't received a reply from Ballmer, she gave a tip of the hat to one of the two Microsoft managers who weighed in on the mailing list.

"The fact that Gray Knowlton from the Office team joined the Patchmanagement.org listserv is a huge start in the right direction towards better communications," Bradley said in an email reply to questions today. "Kudos to Gray for that."

Knowlton, a principal group program manager for Office, gave Microsoft's most detailed account yet for the September screw-ups in a Friday message to the listserv.

"Both of these errors are anomalies in our release operation," said Knowlton. "The XML config[uration] entries had to be hand-authored due to some product code changes. We rarely do this; they are typically machine-generated. In [the blank folder pane in Outlook 2013], a late change to the list of things we intended to ship resulted in a specific configuration not executing as expected."
